D44

Neoplasm of uncertain behavior of endocrine glands

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 9 more specific codes instead:

  • D44.0 Neoplasm of uncertain behavior of thyroid gland
  • D44.1 Neoplasm of uncertain behavior of adrenal gland (also a header)
  • D44.2 Neoplasm of uncertain behavior of parathyroid gland
  • D44.3 Neoplasm of uncertain behavior of pituitary gland
  • D44.4 Neoplasm of uncertain behavior of craniopharyngeal duct
  • D44.5 Neoplasm of uncertain behavior of pineal gland
  • D44.6 Neoplasm of uncertain behavior of carotid body
  • D44.7 Neoplasm of uncertain behavior of aortic body and other paraganglia
  • D44.9 Neoplasm of uncertain behavior of unspecified endocrine gland

What has happened to this code

Every change the publisher made, from 2012 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.

  1. FY2012 Added to the draft code set draft Neoplasm of uncertain behavior of endocrine glands

Official coding rules

Published by CDC for FY2027. A rule attached to a category binds every code beneath it, so the rules inherited from this code's ancestors are shown with the code they come from.

This code

Excludes1 - never coded here

  • multiple endocrine adenomatosis (E31.2-)
  • multiple endocrine neoplasia (E31.2-)
  • neoplasm of uncertain behavior of endocrine pancreas (D37.8)
  • neoplasm of uncertain behavior of ovary (D39.1-)
  • neoplasm of uncertain behavior of testis (D40.1-)
  • neoplasm of uncertain behavior of thymus (D38.4)

Inherited from the D37-D48 section Neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes (D37-D48)

Excludes1 - never coded here

  • neoplasms of unspecified behavior (D49.-)

Note

  • Categories D37-D44, and D48 classify by site neoplasms of uncertain behavior, i.e., histologic confirmation whether the neoplasm is malignant or benign cannot be made.

How CDC's index refers to this code

Wording from the official alphabetic index. Much of it appears nowhere in the code description, which is why a search for the everyday phrase so often finds nothing.
